United States Patent 3,114,460 FURNITURE FASTENING DEVICE Hans linergcns Abranrowslti, Chicago, 111., assignor to Khoury Bros, Inc, Iron Mountain, Mich, a corporation of New .Iersey Fiieii Nov. 9, 1961, Ser- No. 151,600 3 Claims. (Q1. 211-134) This invention relates to fastening devices in the form of hooks for holding furniture in assembled relationship.

At the present time a great many articles of furniture are shipped in knocked down form and assembled by the purchaser in his house or ofiice. This makes possible the shipment of the furniture by express, or even smaller articles by parcel post, instead of the slower and more costly freight. A problem arises, however, in that the buyers of the furniture frequently lack mechanical skill and do not have the tools with which to put the furniture together.

The object of the present invention is to provide a fastening device in the form of a book by which knocked down furniture may be readily assembled and held together.

A further object of the present invention is to provide a fastening device for assembling knocked down furniture which does not require any mechanical skill on the part of or the use of tools by the person assembling same.

Another object of the present invention is to provide a fastening device for assembling knocked down furniture which may be readily made of commercially available material.

Still other objects, advantages, and improvements will become apparent from the following specification, taken in connection with the accompanying drawing, in which:

FIGURE 1 is a front elevational view of an article of furniture having three columns and two tiers of shelves held together by the fastening devices according to the present invention;

FIGURE 2. is an end elevational view of the article of furniture shown in FIG. 1',

FIGURE 3 is an under plan view, partly in section, taken on the section line 3-3 of FIG. 1 and looking in the direction of the arrows;

FIGURE 4 is an isometric view showing two shelves secured to two vertical frame members by the fastening devices according to the present invention;

FIGURE 5 is an isometric view of two of the single fastening devices according to the present invention; and

FIGURE 6 is an isometric view of a double fastening device according to the present invention.

Referring now to the drawings in detail, and to FIG. 1 in particular, there is here shown an article of furniture which is comprised by two end sections, two intermediate sections, and a series of shelves. Each end section is comprised in part by two vertically positioned frame members 10-10, and each intermediate section is comprised in part by two vertically positioned frame members 12-12. As shown in FIG. 2, the end frame members 10-10 are joined together by upper, intermediate, and lower horizontal frame member 11. The intermediate frame members 12-12 are similarly joined together. The lower and intermediate horizontal frame members 11 are secured to the vertical frame members 10-10 and 12-12 by the well known mortise joint; the upper horizontal frame members 11 are secured to the vertical frame members 10-10 and 12-12 by a tongue and slot joint.

As shown in FIG. 1, lower shelves 13 and 17 and a series of upper shelves 10 are secured between the vertical end frame members 10-10 and the vertical intermediate frame members 12-12 in all three columns by 3,114,000 Patented Dec. 17; 1963 "ice the fastening devices according to the present invention. In the left column hinged doors 14 are provided over the front of the compartment between the end frame members 10-10 and the intermediate frame members 12-12 and between the shelves 13 and 17, the hinges for these doors not being shown. One door 14 will be secured by a pair of hinges to the left front end frame member 10 and the other door 14 by a pair of hinges to the left front intermediate frame member 12, when the sections are assembled at the factory.

In the middle column a shelf 16 is provided between the shelves 1 3 and 17. Also a desk lid (not shown) is preferably held by hinges to the shelf 17. In this case the shelf 18 immediately above the shelf 17 will preferably be narrower than the other upper shelves 18 by at least the thickness of the desk lid, so that the desk lid will fit flush with the frame face of the intermediate frame members 12-12 when in the closed position.

In the right column tiers of drawers 20 are positioned in the compartment between the vertical end frame members 10-10 and the vertical intermediate frame members 12-12 and between the shelves 1 3 and 17. These drawers are slidably mounted on runners (not shown), which runners are also secured to the end frame members 10-10 and the intermediate frame members 12-12, when the sections are assembled at the factory.

The vertical end frame members 10-10 are preferably provided with longitudinal grooves from their tops to the lower horizontal frame members 11, the latter frame members are provided with grooves in their tops, and the intermediate horizontal frame members 11 are provided with grooves in their tops and bottoms, all the grooves being aligned in the same vertical plane. A lower panel (not shown) is mounted between the vertical end frame members 10-10 and in the grooves in the latter and between the lower horizontal and intermediat frame members 11-11 and also in the grooves in the latter. Similarly, an upper panel (also not shown) is mounted between the vertical end frame members 10-10 and in the grooves in the latter, and in the groove in the top of the intermediate horizontal frame member 11. This latter panel, however, terminates at the level of the uppermost shelf 18.

The single fastening device according to the present invention is shown in FIG. 5 and is designated generally by the reference numeral 24. This device is used for securing the shelves to the vertical end frame members 10-10. It is made of rod material and is comprised by a horizontal section 24a, a downwardly extending vertical section 24b at right angles to the horizontal section 24a, an outwardly extending horizontal section 240 at right angles to the horizontal section 24a and the vertical section 241;, and an upwardly extending vertical section 24d at the end of the horizontal section 240 disposed in parallel relationship to the first vertical section 24b.

The double fastening device according to the present invention is shown in FIG. 6 and is designated generally by the reference numeral 25. This device is used for securing shelves on both sides of the intermediate vertical frame members 12 to the latter. It is likewise made of rod material and is comprised by a horizontal section 25a, a downwardly extending vertical section 25b at right angles to the horizontal section 25a, oppositely extending horizontal section 250 at right angles to the horizontal section 25a and the vertical section 25b, and upwardly extending vertical sections 25d-25d at the ends of the horizontal sections 25c-25c, disposed in parallel relationship to the first vertical section 2512.

The vertical end frame members 10-10 and the vertical intermediate frame members 12-12 are provided with holes 23 on their inner sides at the levels where the shelves 16, 17, and 18 are to be placed.
